Aaron Brown, who is on trial for manslaughter Picture: Solent News

Carey was driving a Williams Turbojet 325 near a 62ft motor cruiser boat called True Blue in Osborne Bay off the Isle of Wight earlier on the same day that Ryan McKinlay, 36, of Gosport, died.

Mr McKinlay was a passenger onboard the turbojet, a type of Rib, later that day while it was being driven by Aaron Brown, 34, of Botley Road, Curdridge, when it collided with True Blue.

Mr McKinlay, a friend of Brown’s, died at the scene on June 19, 2015.

Brown is charged with manslaughter by gross negligence, which he denies.

Jon Mendez, an experienced boating instructor, who also owns Mendez Marine in Hamble, gave his expert opinion about how the RIB was being driven after watching video evidence.

Mr Mendez, a trainer and examiner for the Royal Yachting Association, said: ‘They were having nice afternoon. People were enjoying themselves on the water and I don’t think he was acting unduly dangerously.’

Mr Mendez said he had experience of driving the same make and model turbojet.

He added: ‘It’s highly manoeuvrable, it is very dextrous and it can turn on a sixpence when asked.’

The jury was shown footage of Carey driving past True Blue.

Mr Mendez estimated them to be travelling at approximately 15 to 16 knots - or 17 to 18 miles per hour - and approximately eight to nine foot away from True Blue.

He said: ‘Mr Carey was asked to give a fun ride to the people, to me he did so and he drove in quite a sensible manner… He was never aiming the boat and the sea conditions were not enough to deflect it… His momentum was going away from True Blue.’

He said that Carey had several options for avoiding True Blue despite being so close, such as steering away or immediately closing the throttle.

Mr Mendez added: ‘He has obviously intended to turn to the left away from True Blue, that’s his emergency get-out-of-jail card and he’s already worked that out. That’s why he has done it.’

The court will hear more evidence this afternoon in relation to the interview given by Carey at the time.
